           Summary: Function-local static/shared static data must be

                    termination

This is an important core language issue because a fundamental invariant is
that data is being destroyed appropriately.

Most C++ implementation use atexit() to queue destruction of function-level
statics. I assume the new thread_local C++ facility is typically implemented
with the help of pthread_key_create().

We need to devise the appropriate mechanisms.
